15. SSH

To get remote access of IOT device, you should have Teleport installed on device and then you can create SSH tunnel as mentioned below:

SSH Tunnel​

  1. Connect to teleport, install Ngrok and execute ngrok tcp 22 command, it will show you tcp forwarding line such as tcp://8.tcp.ngrok.io:12112 -> localhost:22
  2. Then connect your local terminal and execute SSH tunnel command as ssh -L 0.0.0.0:3000:0.0.0.0:3000 root@8.tcp.ngrok.io -p 12112 [Note: replace actual values & port 3000]
  3. You will be asked to enter root password. [I assume you have it.]
  4. Then open http://localhost:3000 in the browser so basically we have forwarded whatever service running on 3000 port.
